SPECIFICATION forming part of Letters Patent No. 396,386, dated January 22, 1889,

i Application filed February 25, 1888. Serial No. 265,334. (No model.)

To all whom it may conccrwp Be it known that I, FRANK A. BAscoM, a cit-i- Zen of the United States, residing at Greenville, in the county of Mercer and State of Pennsylvania., have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in that class of sash fasteners and suppoi ters in which a sector actuates a wedge by means of a lever; and the object of my invention is to produce a sash fastener and supporter which is very simple in its construction, not liable to lget out of order, and reliable in its operation; also, to actuate a rough'ened wedge in such manner t-hat it can be arranged to prevent the raising' of the window-sash by force, especially from the outside; also, to produce a very strong device that will not b e easily p broken; furthermore, to furnish a sash fastener and supporter that can be readily applied to old win dow-sashes now in use, as well as to new ones, and without defacing the sash or frame, and, linally, to produce a very inexpensive device which will not disiigure the appearance of the window sash or frame.

lVitih these objects in view my invention consists in the construction ol certain details and arrangement of parts, as will be more fully described hereinafter, and specifically pointed out in the claims, reference being had Vto the accompanying' drawings and the letters of reference marked thereon.

Like letters indicate similar parts in the different figures of the drawings, in which- Figure l represents a side elevation of my sash-fastener. Fig'. 2 is a front view of the same. Fig. 3 is a side view, with halt' ot the housing' removed to expose the interior parts in a raised position. Fig. i is a front, rear, and side view of the wedge. AFigs. 5, 6, and 7 are detail views of the sector and actuatinglever. Figs. S, il, and lO are detail views of the housing'. Fig. l1 is-a detail view of a modified wedge and lever.

In the drawings, A represents the housing or casing, which is, for convenience, made in two parts riveted together by suitable rivets.

In this housing a wedge, B, provided on its face with points b and on its rear side with a depression, c, and a series of short cogs or teeth, d, is placed and is free to move up and down. Vith said teeth d a sector, C, journaled in bearings f, secured or cast to the sides of the housing' and having a double set of teeth, c, engages. On one side the journal projects through the housing', and is preferably iiattened, or it may be squared, as at g, to which the actuating-leverD is secured and prevents it from turning. The wedge Bis pro vided at its upper corners with short projections or ears h, which engage with the slots E in the sides of the housing. The slots are made of such shape as to permit the wedge in its movement up and down to accommodate itself to the radius of the sector C. The teeth on the sector are divided by a partition, i, and said teeth are staggered, so that the teeth on one sideof the partition are placed opposite to the spaces on the other side. By arranging the teeth in this manner there will be no jarring, or what is technically called backlash, and it causes a steady sliding mot-ion of the wedge.v This wedge is provided with flan ges 7c, which move in guides l, formed in the sides of the housing and serve to steady it in its sliding motion.

It' desired, the face of the wedge may be serrated or roughened in any other suitable manner, so as to prevent slipping or sliding of the window-sash. The lever is preferably constructed in such manner that it will automatically descend by gravity, thus forming a gravitating or weighted lever. Any suitable material may be employed in the manufacture of the device, and it maybe made plain or ornamental. The rattling of windows is also prevented by my device, and the device forms an automatic lock in windows with weights and cords.

The operation is as follows: The device being lirst connected with the teeth of the sector meshing' with those on the wedge, and the parts of the housing riveted together, the device is secured in position in the window-- frame. If. it is desired to raise the windowsash, the actuating-lever is raised and with it the wedge, which permits the sash tov be moved up and down until the lever is released, which IOO causes the points on the Wedge to engage with the side of the frame and hold the sash in any position. To reverse the devioe will prevent raising of the sash from the outside hy force by placing it in the Window-sash.

IL ving thus d eserihed my invention, what l Claim iS- l. In a saslr't'astener, 'the combination of :L housing with a sector mounted therein, n Wedge guided in slots in said housing, and e `grevitating lever for operating the seme, suhstantially as specified.

2. The combination of a h'seeted housingl having,` slots therein with the wedge seated in said slots and provided with teeth on its rear side, zt sector, also provided with teeth to engage the teeth of the Wedge, and zt gravitztting lever for operating the salme, substantially as and for the purpose set forth.

In a sash-fastener, the Combination of the housing with the Sector, C, having 2t double set of teeth, the Wedge B, having e double set of teeth on the beek thereof, said teeth being adapted to engage the teeth of the sector, :tud a. gravitating lever, substantially as set forth.

et.' The housing` A, provided with slots E and guides l, in Combination with the Wedge l, having lugs 71, Henges 7c., to engage with said slots and guides, and provided with teeth l1, a double sector meshing with the teeth ot' said wedge, mld a gravitating lever, D, connected therewith, substantially as and for the purpose set forth.

In testimony whereof I hereby affix my signature in, presence of two Witnesses.
